This equation shows how the time required to screen-print a batch of shirts is related to the number of shirts in the batch.

t = s + 3

The variable s represents the number of shirts in the batch, and the variable t represents the time required to screen-print the shirts. How long does it take to screen-print a batch of 6 shirts?

1 answer

To find the time required to screen-print a batch of 6 shirts, substitute \( s = 6 \) into the equation:

\[ t = s + 3 \]

Substituting 6 for \( s \):

\[ t = 6 + 3 \]

Now, calculate:

\[ t = 9 \]

Therefore, it takes 9 minutes to screen-print a batch of 6 shirts.
